📺 Demo #
🔩 Basic Demo #

FRadio(
value: 1,
groupValue: groupValue_1,
onChanged: (value) {
setState(() {
groupValue_1 = value;
});
},
),

FRadio(
value: 2,
groupValue: groupValue_1,
onChanged: (value) {
setState(() {
groupValue_1 = value;
});
},
)

A regular FRadio is very simple to build. You only need to configure:
value: It will indicate the current value represented by FRadio.
groupValue：Indicates the selected value of the current radio group.
onChanged：When selected, it will callback. In this callback, you need to assign the value value of FRadio to the radio group groupValue to complete the switch of group options.

💡It is worth noting that FRadio will only be selected when groupValue == value. This is very flexible, that is to say, you only need to change the groupValue to switch options at will.

👀 Enable & Toggleable #

FRadio(
value: 1,
groupValue: groupValue_2,
onChanged: (value) {
setState(() {
groupValue_2 = value;
});
},
toggleable: true,
enable: enable_1,
selectedColor: Color(0xffffc900),
),
copied to clipboard
Through the enable attribute, you can control the availability of FRadio. When FRadio is not available, the unavailable style will be displayed. They of course include selected and unselected.
The unavailable styles of FRadio built by the default constructor are grayed out.
If you want to build different unavailable styles, you can configure disableNormal (unchecked unavailable styles) and disableSelected (check unavailable styles) through the FRadio.custom () constructor.
FRadio will allow the user to cancel the selection, which can be achieved by configuring toggleable: true. Of course, by default, we do not open this feature.
🔆 Space & Corner & Border #

FRadio(
width: 100,
height: 50,
value: 1,
groupValue: groupValue_3,
onChanged: (value) {
setState(() {
groupValue_3 = value;
});
},
selectedColor: Color(0xffffc900),
corner: FRadioCorner(leftTopCorner: 6, leftBottomCorner: 6),
border: 1,
hasSpace: false,
selectedChild:
Text("FSuper", style: TextStyle(color: Color(0xff333333))),
child: Text("FSuper", style: TextStyle(color: Color(0xff333333))),
)
copied to clipboard
In this chestnut 🌰, FRadio shows several abilities that are not possible for radio components.
Through the corner attribute, you can accurately control the corners so that FRadio is no longer a circle.
hasSpace gives you the freedom to choose whether you want to keep the distance between the inner padding and the edges, as it is by default.
Usually, FRadio has a set of exquisite calculation methods internally to provide a very beautiful view. By default, FRadio will automatically calculate the width of the border to maintain a harmonious aesthetic.
But you can still configure it as needed through the border attribute.
🌈 Gradient #

FRadio(
width: 50,
height: 50,
value: index + 1,
groupValue: groupValue_4,
onChanged: (value) {
setState(() {
groupValue_4 = value;
});
},
gradient: LinearGradient(
colors: [
Color(0xffFEFDBB),
Color(0xffFFE16C),
Color(0xffEA9D1C),
Color(0xffD46307),
],
begin: Alignment(-0.1, -0.9),
end: Alignment(1.0, 1.0),
stops: [0.0, 0.2, 0.7, 1.0],
),
selectedColor: Color(0xffffc900),
hasSpace: false,
border: 1.5,
child: Text(
"\$${5 * (index + 1)}",
style: TextStyle(color: Color(0xffd9d9d9), fontSize: 13),
),
hoverChild: Text(
"\$${5 * (index + 1)}",
style:
TextStyle(color: Colors.deepOrangeAccent, fontSize: 13),
),
selectedChild: Text("\$${5 * (index + 1)}",
style: TextStyle(
color: Colors.deepOrangeAccent, fontSize: 13)),
)
copied to clipboard
You see, this is the magical use of gradients.
gradient accepts multiple types of gradient configurations. If you plan to make the radio view look more colorful or more spatial, you can try it.
🍭 Decoration #

FRadio(
width: 80,
height: 80,
value: 1,
groupValue: groupValue_5,
onChanged: (value) {
setState(() {
groupValue_5 = value;
});
},
child: Image.asset("assets/emoji_0.png", width: 50),
hoverChild: Image.asset("assets/emoji_1.png", width: 50),
selectedChild: Image.asset("assets/emoji_2.png", width: 50),
hasSpace: false,
toggleable: true,
selectedColor: Color(0xffffc900),
border: 1.5,
)

FRadio magically makes the entire radio no longer boring!
child and selectedChild configure the top-level decorative components.
How is the mouse hover effect constructed?
The border color will automatically accept the selected color configured by selectedColor when hovering. The decoration can be configured through hoverChild.
When hoverChild is not configured, the selected state decoration configured by selectedChild will be accepted.
how about it? This is so interesting!
🎨 This is customizable! #

If the default constructor does not satisfy you, what else do you need?
By the way, Customize!
Through the FRadio.custom () constructor, you can configure the style of FRadio in different interactive states through: normal, selected, disableNormal, disableSelected, hover.
This will untie the hemp rope in your hand, you are free, and you can start to create at will.

ListView.builder(
itemCount: list.length,
itemBuilder: (context, index) {
return FRadio.custom(
value: index,
groupValue: groupValue_7,
onChanged: (value) {
setState(() {
groupValue_7 = value;
});
},
normal: Container(
width: 250,
height: 100,
color: Colors.white,
padding: EdgeInsets.only(left: 12, right: 12),
child: text(index),
),
hover: Container(
width: 250,
height: 100,
color: Color(0xff212121).withOpacity(0.05),
padding: EdgeInsets.only(left: 12, right: 12),
child: text(index),
),
selected: Container(
padding: EdgeInsets.only(left: 12, right: 12),
color: Color(0xff607D8B).withOpacity(0.2),
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text("${list[index]}"),
Icon(
Icons.check,
size: 18,
),
],
),
),
);
},
)
